From the Richmond Dispatch, 9/25/1862, p. 2, c. 3

Military. – We understand that the
object in seizing on all soldiers round on the streets — a process
which has been going on for several days — is to enforce a
regulation lately made requiring all who have authority to stay in
Richmond to procure a pass from the office of Major General Gustavus
W. Smith, which is located in Belvin's block, on 12th street. For
the information of military men to be affected thereby, we may state
that the command of Gen. Smith extends South of the line of Gen.
Lee's operations, and embraces North Carolina. All commanding within
those limits report to and receive their orders from his
headquarters.
